We revisit the calculation of holographic correlation functions in type-IIB supergravity on AdS_{5}×S^{5}. Results for four-point functions simplify drastically when expressed in Mellin space. We conjecture a compact formula for the four-point functions of one-half Bogomol'nyi-Prasad-Sommerfield single-trace operators of arbitrary weight. Our methods rely on general consistency conditions and eschew detailed knowledge of the supergravity effective action.
我们重新审视了IIB型超引力在AdS₅×S⁵上全息关联函数的计算。当用梅林空间表示时，四点函数的结果大幅简化。我们推测了任意权重的二分之一博戈莫尔尼-普拉萨德-索末菲单迹算符四点函数的一个紧凑公式。我们的方法依赖于一般的一致性条件，避免了对超引力有效作用量的详细了解。
